MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 444,283, dated January 6, 1891.,

Application filed September 4, 1890- Serial No. 863,882. (No model.)

To all whom it may concern.-

Be it known that I, ALBIN WARTH, a citizen of the United States, residing at Stapleton, in the county of Richmond and State of New York, have invented new and useful Improvements in Mechanical Movements, of which the following is a specification.

This invention relates to certain improvementsin that class of mechanical movements which are described in Letters Patent No.

151,457, granted to me May 26, 1874;. and the improvements which form the subject-matter of my present application for a patent are pointed out in the following specification and claims, and illustrated in the accompanying drawings, in which Figure 1 is a plan or top view. Fig. 2 is a front elevation. Fig. 3 is a transverse vertical section in the plane x 00, Fig. 1. Fig. 4 is a partial vertical section in the plane y y, Fig. 1, on a larger scale than the previous figures. Fig. 5 is a similar section in the plane 2 z, Figs. 1 and 6. Fig. 6 is a similar section in the plane 5 2', Figs. 3 and 5. Fig. 7 is a face view of the carriage detached. Fig. 8 is a sectional view on a large scale, showing a cutting-tool as may be used in connection with my invention.

In the drawings, the letters A A designate two tables, and B is a guide or rail, which is situatedbetweenthetwotables,andwhichmay be fastened to one of said tables or to the floor or to the walls, according to circumstances. On this rail is placed a carriage D, which 1s by preference provided with two pairs of wheels to a, engaging the rail from opposite sides, and which is retained in an upright position by means of a rod 1), on which are mounted two wheels 0 c, which bear on the opposite sides of a rail 0, Figs. 2 and 3, running parallel with the rail B. The wheelsc c are mounted in a bracket 0, which is secured to the rod 1), and from which extends a slotted arm 0 which straddles the rail 01 and-is mounted a two-speed pulley d (Z and on the driving-shaft E is firmly mounted a pulley 6,

round which extends a belt F, which runs over a guide-pulley f, the speed at, the guidepulleyf', thence down beneaththe pulleyf and over the pulley f thence beneath the speed cl, and over the guide-pulleyf back to the driving-pulley e. The pulleys f andf" are mounted on brackets f and f respectively, (best seen in Fig. which are secured on a fixed rod or post f by .means of setscrews, so that they can be adjusted in order to increase or decrease the tension of the belt F. In the same manner the pulleys f and f are mounted in brackets f and f which are secured to a fixed rod or post f by means of setscrews, so that by adjusting these brackets the tension of the belt F can be regulated.

On the stud cl near its outer end is mounted a bracket g, which carries a dog g, and between the bracket 9 and the pulley d is situated a bar 9 which turns freely .upon the stud cl and is provided in one of its edges with ratchet-teeth g (see Figs. 2 and 7) in a position to enable the dog 9 to engage with them. Said bar 9 carries two pulleys g 9 which, when the bar is turned upon the stud, act upon'the belt F in such a manner that the pulley g depresses the upper branch of said belt upon the pulley (1', while the pulley g forces the lower branch of said belt up against the pulley d, and since the bar gcan be adjusted by means of the dog g the action of the belt F upon the pulley d can be regulated as may be desired. From this description it will be seen that the carriage D can be moved from one end of the rail B to the other without throwing the pulley cl out of engagement with the belt F, and at the same time a revolving motion is imparted to the pulley d as long as said belt is in motion.

On the carriage D is formed orsecured a platform 61 (best seen in Fig. 4,) which is provided with a tubular projection dfl engaging an arm H, which I shall designate hereafter as the supporting-arm. This arm is fastened on the platform d by means of a screw-bolt d, and if the nut of this screwbolt is loose the supporting-arm is free to swing on the tubular projection cl ,'but it can be locked in position by means of a latch h,

Lil

which is attached to it by a set-screw h, and which, when depressed, engages a recess in the platform (1.

On the inner end of the supporting-arm ii is mounted the balance-arm I, the connection being such that said balance-arm can freely swing both in a horizontal and also in a vertical plane. Said connection consists of a plate 71?, which is firmly secured to the supporting-arm ll, and upon which is placed a bracket 71., provided with two lugs 7t (best seen in Fig. (3,) and with a tubular projection 71, which forms the bearing for an arbor 7L6, on which are mounted two pulleys h 71. which are firmly connected to each other. The balance-arm I rests upon a plate 1', which is provided with downwardly-prejecting lugs 11' I", and is connected to the bracket 7/. by pivots '1? i", which extend through the lugs 7t and I and both the balance-arm I and the plate i are provided with slots 2" 1', respectively, which engage the tubular projections 7r of the bracket h. The plate 1' is made to extend in the direction of the length of the balancearm, (see Fig. 5,) and from this extension rise lugs 1", which engage the slot 1', so as to steady the balancearm. A screw-bolt serves to fasten the balance-arm upon the plate 1' in the desired position.

On the balance-arm at or near one of its ends is secured a weight .l, and on its opposite end is attached a tool K, which may be a device for cutting cloth, or a grinding-wheel, or any tool which does its work while in motion over different parts of the articles to be acted upon. On the balance-arm is also mounted a shaft L, which is geared together with the tool K. On the shaft L is mounted a pulley 7, which connects by a belt I with the pulley h Figs. 3 and G, mounted on the arbor 7i. Motion is transmitted to this arbor from the pulley (1 which is loosely mounted on the stud d in the carriage D, Fig. and firmly connected to the pulley d, to which motion is imparted by the driving-belt F, as above explained. Over the pulley d extends a belt 31, which passes down under two pulleys m in, secured to the rod Z2, Fig. i, thence up over two pulleys m an, mounted on the opposite sides of the supporting-arm II, and thence around the pulley h mounted on the arbor 7/". It will be readily seen from this description that the weight J forms a balance for the tool G, and by adjusting the balance-arm in the direction of its length by means of the slot i and screwbolt i the pressure exerted by the tool upon the table or upon the work over which it moves can be adjusted. At the same time by connecting the balance-arm I to the supportingarm 11, I am enabled to move the tool over a table of considerable width with a comparatively short balance arm, and when the tool is moved over the table that end of the balancearm which supports the weight J does not swing beyond the edge of the table, so that it will not interfere with the work of persons engaged near said table. Furthermore, by connecting the sup )orting-arm It to the carriage I D, I am enabled to move the tool over every part of the table without throwing the same out of gear with the driving-shaft E.

If it is desirable to use the tool while the carriage D is held stationary, said carriage can be moved over the rail B into the desired position and fastened by means of the setscrew c, Fig. 1, without throwing the pulley (Z' out of gear with the driving-shaft, and in that case the nut of the screw-bolt (l is loosened, so that the supporting-arm II can swing on the tubular projection d and the tool can be carried over a large portion of the table orof the work on which it is to act, while the pressure of the tool upon the work is counteracted by the balance-arm. The range of the tool over the work 2 can be still further increased when the screw-bolt '11 is released, so that the balance-arm can slide in the direction of its length. It must also be remarked that the weight J may be made integral with the balance-arm without departing from my invention; but I prefer to make the weightJ detachable from the balance-arm, so that it can be adjusted on the same, as may be desirable.

The tool which I have shown in the draw ings is a knife for cutting out garments such as shown and described in Letters Patent Nos. 380,962 and 380,003, granted to me April 10, 1888, and a reciprocating motion is imparted to this knife from the shaft L by means of a pitman 1', Figs. 1 and S. This pitman engages a crank 8, formed on the shaft L, and it connects with a bell-crank lever 9, which engages a sleeve 10, fitted upon a pillar 12 and engaging lugs 12), which project from the bar of the knife 11-. A tool may, however,be used which requires a revolving motion, and the devices for transmitting such motion to the tool from the shaft L will readily suggest themselves to any ordinary machinist.

I do not claim in this application anything claimed in my applications, Serial Nos. 363,883 and 363,881, bearing even date with this.

What I claim as new, and desire to secure by Letters Patent, is
